i tried to use the imagettfbbox function to get the width and height for my text. after doing some work everything was fine on my linux machine. when i now run the same script on a windows machine the image looks really bad.
so i made a simple testscript and compared the result:
$e = imagettfbbox(12, 0, './Roboto-Regular.ttf', "e");
on windows i got
Array
(
[0] => -1
[1] => -1
[2] => 8
[3] => -1
[4] => 8
[5] => -10
[6] => -1
[7] => -10
)
on linux i got
Array
(
[0] => -1
[1] => 0
[2] => 8
[3] => 0
[4] => 8
[5] => -11
[6] => -1
[7] => -11
)
does anybody know i solution how to get the same values out of this command, maybe with some dirty calculation tricks?
